Which is the equivalent reciprocal of cot 75 ?
Answer:
What is the Value of Cot 75 Degrees in Terms of Tan 75°? Since the cotangent function is the reciprocal of the tangent function, we can write cot 75° as 1/tan(75°). The value of tan 75° is equal to 2 + √3.
Use the Pythagorean Identity and Tangent Identity to find tan theta if sin theta= -1 and 0 ≤ theta <2Pi radians.
By using the Pythagorean identity the value of tan [tex]\theta[/tex] will be ∞.
tan [tex]\theta[/tex] = ∞.
What is Pythagorean identity?
Pythagorean identities are identities in trigonometry that are extensions of the Pythagorean theorem. The fundamental identity states that for any angle [tex]\theta[/tex],
[tex]sin \; ^{2} \theta + cos \; ^{2} \theta =1[/tex]
By Pythagorean Identity we have,
[tex]sin \; ^{2} \theta + cos \; ^{2} \theta =1[/tex]we have, [tex]sin \theta \; = \; -1[/tex]
So, [tex](-1)^{2} \; + \; cos^{2}\; \theta =\; 1[/tex]
[tex]\; cos^{2}\; \theta =\; 1 - \; 1[/tex]
[tex]cos^{2}\; \theta =0[/tex]
[tex]cos\; \theta =0[/tex]
Now, we know that
[tex]tan \; \theta= \frac{sin\; \theta}{cos\; \theta}[/tex]
= [tex]\frac{-1}{0}[/tex]
[tex]tan \; \theta=[/tex] ∞....................... (1)
Again, tan [tex]90^{0}[/tex] = ∞
If we compare from equation (1), we have
[tex]\theta = 90^{0}[/tex]

What is the solution to this system of linear equations? x y = 4 x − y = 6 (4, 6) (6, 4) (5, −1) (−1, 5)
The solution to the system of linear equation x + y = 4 and x - y = 6 is (5, -1).
How to find the variable in a system of equation?
x + y = 4
x - y = 6
Therefore, let's add the equations.
2x = 10
divide both sides by 2
x = 10 / 2
x = 5
Let's find the value of y

A cylinder has a height of 9 meters and a diameter of 12 meters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth. please helpppp
Answer:
1,017.36
Step-by-step explanation:
To find the volume of a cylinder, you need to figure out the radius and height.
We've already been given the height, which is 9 meters.
Now let's find the radius.
To find the radius you have to divide the diameter by 2, which means 12/2, which is 6.
Now let's plug it into the formula: [tex]V = \pi r^{2} h[/tex]
So, 3.14 x [tex]6^{2}[/tex] x 9.
Solve the exponent, giving us 36.
3.14 x 36 x 9 = the volume.
Meaning, V = 1,017.36

A rectangular coil of wire, 22. 0cm by 35. 0cm and carrying a current of 1. 95a , is oriented with the plane of its loop perpendicular to a uniform 1. 50 t magnetic field
If the plane of the loop is perpendicular to the magnetic field then the θ will be zero. Then the torque will also be zero.
What is torque?The torque that may cause an item to revolve along an axis is measured as torque. The axis of rotation is the point at which the item rotates.
A rectangular coil of wire, 22.0cm by 35.0cm and carrying a current of 1.95 Ampere, is oriented with the plane of its loop perpendicular to a uniform 1.50 Tesla magnetic field.
Then the torque that the magnetic field exerts on the coil will be
The torque is given as
[tex]\rm \tau = I \overrightarrow{A} \times \overrightarrow{B}[/tex]
The strength of magnetic torque on the current-carrying circle is given by θ: if θ is the angle between A and B. Then we have
[tex]\rm \tau = I AB \sin \theta[/tex]
When the loop plane is perpendicular to the magnetic field, the amplitude of magnetic torque on the current-carrying circle is zero.
Then θ = 0
Then we have
[tex]\rm \tau = I AB \sin 0\\\\\tau = 0[/tex]

what is pi and why do we need it
Answer:
See below
Step-by-step explanation:
π, pronounced as pi is the ratio between 2πr which is circumference to 2r which is diameter.
In word, π is circumference/diameter which has exact value of 3.14159... and it is also an irrational number too.
π is often used to be defined as 3, 3.14 or 22/7 [Keep in mind, these numbers are only approximation.] in some fields. In trigonometry, π is mostly used to refer as π radians or π rad which is equivalent to 180°.
Why do we need it? Because it’s useful in a field that requires rotation. If you notice, figure with circular base will always have π with it, the volume is an example.
In calculus, you need π to do solid of revolution method which is:
[tex]\displaystyle \large{V =\pi \int\limits^a_b {[f(x)]^2} \ dx }\\\\\displaystyle \large{V = \pi \int\limits^a_b {[g(y)]^2} \ dy}[/tex]
In trigonometry, you need it for measurement/angle.
So anything that’s related to revolution, rotation or related to circle must require π at least.
In general life, you do not use it but this is mostly applied in engineering field and anything related to science that involves with circle or revolve.

Given that;
The area of the triangle below is 23.66 square inches.
And, The height = 5.2 inches
We know that;
Area of triangle = 1/2 × Base × Height
Substitute all the values we get;
⇒ 23.66 = 1/2 × Base × 5.2
⇒ 23.66 = Base × 2.6
⇒ Base = 23.66 / 2.6
⇒ Base = 9.1 inches
